You have high NBA expectations and the results are — shall we say — not high, you study all avenues of change.

And the Nets are doing exactly that, exploring all trade options, including those involving their three best players, Deron Williams, Joe Johnson and Brook Lopez, multiple league sources confirmed.

“When you are 8-11, you look at all possible options,” one league source said.

So as a matter of course of doing business in the NBA, the 8-11 Nets, who face the Bulls in Chicago Wednesday without Johnson (flu) and Lopez (back), have made and received exploratory calls on the availability of their Big Three. They have made contact here and there and kicked the tires, but are nowhere near to completing anything on that front.

“After the last stretch,” one opposing executive said, “they have been very active in calling around. I think they are ready to deal but I haven’t heard of anything that is close to being done.”

The Nets, after beating their first opponent with a winning record, the defending champ Spurs, lost at home to the Hawks and Cavaliers by 45 combined points.

On another front, the Nets have resumed talks with the Sixers concerning Andrei Kirilenko, sources confirmed after Yahoo Sports reported the renewed talks. The Cavs also had been linked to interest in Kirilenko.

The Sixers want a second-round draft pick and would take on Kirilenko and his $3.3 million contract, then likely waive him. The Nets, who would receive a $3.3 million trade exception, would save upward of $12 million with luxury-tax considerations. Kirilenko, whose wife is going through a rough pregnancy, has made it known he cannot travel, which makes the Nets’ ability to fetch a player in any deal virtually nil. So if you can’t land a player, get financial help, and the Nets appear to be trying that route.

Again, it goes with the territory. ESPN.com reported Tuesday about the wave of calls concerning Johnson, Williams and Lopez.

“[The Nets] have explored all options at this time which [they] are supposed to do,” another league source claimed.

The Nets, who in Lionel Hollins have their seventh coach since 2009 and fourth since the move to Brooklyn in 2012, had a $193 million payroll last year in salary and luxury tax and got a first-round playoff series victory in return. They still lead the league in salary alone at $94 million, topping the second-place Knicks ($90 million).

Just nine days ago, Nets general manager Billy King acknowledged “tweaks” might be needed on the current roster and admitted to making calls. Of course, if he were not making calls, that would be news.

“We’re on the phones, we’re talking to people but there’s nothing imminent,” King said at the time. “This group has proved that they can play good basketball and so, at this point, it’s up to them to figure it out.”

But asked if the Nets could win with their Big Three, King said simply, “We’ll see.”

Johnson has one year at $24.8 million beyond this season, when he makes $23.1 million. Lopez has this season ($15.7 million) and next season — with a player option for $16.7 million. Williams, earning $19.7 million this season, will make $21 million next year and is due $22.3 million in 2016-17, but can opt out and become a free agent in 2016.
